Application March l, i954, Serial No. illm l Claim. (Cl. Z22- 519) This invention relates to improvement in faucets, and more particularly to faucets for withdrawing liquids from containers, such as casks or drums.

lt is an obiect of this invention to provide an improved faucet of the above mentioned character which operates in an expanded position for withdrawing liquids from a container` and which has sealing means for maintaining the faucet tight against leaks.

Another object of the invention is to provide an improved faucet of the above mentioned character which is adapted to receive a lock means for sealing the faucet in a closed position.

Other objects and advantages of the invention will be apparent during the course of the following part of this specification, wherein the details of construction and mode of operation of a preferred embodiment of the invention are described with reference to the accompanying drawing, in which:

Figure l is a Vcentral vertical longitudinal section through a faucet embodying the invention, and mounted in a wall of a drum;

Figure 2 is a section similar to that of Figure l but showing the faucet in its expanded position for discharging liquid from the drum;

Figure 3 is an end elevation of the faucet looking in the direction of the arrows on line 3 3 of Figure l;

Figure 4 is a transverse section through the faucet on an enlarged scale and taken on line 4 4 of Figure 2; and

Figure 5 is a detail cross section taken on line 5 5 of Figure 2.

Referring now to the drawings more in detail and by reference numerals, an end wall of a container, and more particularly a drum, is designated by numeral and such end wall is joined to a side wall l1 of the drum by a usual chime construction as shown at 12. There is an opening 13 in the end wall of the drum for receiving a faucet designated generally by the numeral 14. Welded or otherwise suitably secured on the inside face of the end wall and in axial alignment with the opening 13, is a collar l5 having an internally threaded opening 16 for mounting the faucet in the drum wall.

The faucet comprises a cylindrical oute'rbody member 1S which is externally threaded to mate with the screw threads in the collar opening i6. For turning the faucet in the collar opening, the body of the faucet has a non-circular head 19 on the forward end thereof. The head 3.9 is of larger diameter than the body 18 thus providing an inside face of the head for engagement with the outside face of the drum wall around the drum opening i3 whereby the head 19 cooperates with the collar l5 in holding the faucet on the drum. There is an axial bore 2l extending through the body member i8 making an open-ended tube of the body member. A tapped counterbore 22 of shorter axial length and of larger diameter than the main bore 2l extends coaxially with the main bore from the head end of the body.

Rotatable and slidable axially in the main bore 2l is a stern 24 having a circular end plate 25 on its forward end and a rib or handle member 26 extending diametrically of the outer face of the end plate. The neck of the stern, which is designated by numeral 27, is of larger diameter than the cylindrical body of the stem and is externally threaded for engaging the threads of the counterbore 22 For accommodating the head of the stem, i.e., end pla a5 and handle 26, the head 19 of the main body part i8 of the faucet has a cavity 29 of circular cross-section and of sufficient depth that when the neck of the stem is screwed into the counterbore 22 the handle member Z6 does not extend outwardly beyond the rim of the cavity. Thus the head i9 is cup-shaped, that is, it has an annular wall 3ft? which defines the cavity, and the axial dimension of the head is less thanpthe length of the chime l2 so that when drums having faucets as herein shown are stacked end on end, the faucet heads are protected by the chimes of the drums from being broken or otherwise damaged.

From that end of the stem which is located in the interior of the drum, and for descriptive convenience is designated by the numeral 3l, there is a cylindrical bore 32 extending axially into the stem to a point 53 adjacent the neck portion of the stem. The interior or tail end 31 of the stem bore is closed by a plug 35 which is suitably xed in the end of the bore 32 as by a pin 36. The plug 35 not only closes the tail end of the stem but also extends axially beyond the stem and has a circular disc 37 on its outer end which is engageable with the tail end of the body l for providing a stop means which limits outward movement of the stem from the body when the stem is moved to its liquid discharging position as shown in Figure 2 of the drawing. The extent to which the stem may be withdrawn from the head end of the body is predetermined by the dimension of that portion of the plug which extends beyond the tail end of the stem.

The cylindrical bore 32 in the stem forms a section of a passageway for liquid to flow through the stem to a radially extending discharge opening 39 communicating with the forward end of the bore 32. The discharge opening 39 is located in the faucet at a point where it will extend beyond the rim of the chime l2 of the drum when the flanged end 37 of the plug is stopped against the tail end of the body member i8.

in the wall or' the stern and adjacent the tail end thereof are radially extending inlet openings -ttl located at a place in the stern where each such opening will be in registry with one of a series of circumferentially arranged apertures 4l in the wall of the tubular body portion i3 when the stem is moved outwardly to its liquid discharge position as predetermined by the length of the plug 35. Thus when the faucet is expanded so that the ange 37 abuts against tail end of the body member lil t0 thereby prevent further outward movement of the stern from the body, a passageway for discharging liquids from the interior of the drum is opened, such passageway comprising an aperture 4l, an inlet opening 49, bore 32, and discharge opening 39.

An important feature of the faucet of this invention is the provision of sealing means preventing leakage from the faucet around its stem. To this end there is an annular groove 43 formed in the outer surface of the stem and lying in a plane transversely of the stem and adjacent the neck portion of the stem. The groove 53 receives an O-ring dal or gasket of "ynthetic rubber or other suitable sealing ring material which can withstand corrosive attack from oil or gasoline or acid and the like. When the stem is in its faucet closed position as shown in Figure l of the drawing, the outer periphery of the G-ring 44 becomes pressed against the walls of the main bore 2i and the walls defining the groove 43 to constitute a leakproc-f seal preventing leakage or liquid through the main bore and through the head end of the faucet. The O- ,Y ,Y ring 44 is carried by the stem outwardly ofthe bore Y when the stem is .extended to its liquid discharge position,

and thus the O-ring must be slightly contracted and forced into the main bore 21 each time the kfaucet'is Y closed. To prevent cutting of the outer periphery of the O-ring by the rim'of the main bore, the inner end ofthe counterbore 22 is chamfered, as shown at 45,10 Vform an annular beveled shoulderraround the rim of the main whore',V

thus providing for moreigradual contraction of the O1 Y ring when it is forced into the main bore, and such beveled construction of the shoulder 45 eliminates the likelihood i of cutting the O-ring. Arranged inwardlyofrthevOring`4 'is another Gering 47 which instead of being Vcarried by the stem, as is the Y @ring 44, is mounted in an annular Agroove 48 which extends, in a plane transversely of theinterior wall Vdening themain ,borerlf TheI O-ring Y47V is 'slightly ex-V panded in`r encirclingthestem which is axially slidable in the O-ring. Like the O-ring 44, the ring Leconstitu'tes a sealing gasket formed 'of synthetic' rubber or other suitable gasket material.

-As explained above, the faucet head i9 is cup-shaped so as to receive the'faucet handle 26.Y VDuring shipment of lthe drurnsrit'is desirable to seal the'faucet in its closed position and for this purpose the handle 26 hasa centrallyV arranged aperture S2 passing through the handle. Likewise, Vthere is a series of circumferentially arranged radi. .Y ally extending apertures 53 in the annular. wall 3Q. of the head, and these Ypermit 'a sealing. wire (not, shown) or other lock means to be passed through theV aperture 52 through opposite and aligned apertures 53 inthe head of the faucet, requiring'that the sealing wire be` severed,Y

or withdrawn prior to openingthe faucet.

While theV instant invention'has been shown and described hereinY in what'isfconceived to be the most practical and preferred embodiment, it is recognized Ythat departures may be made therefrom within the scope of the invention, which is therefore not to be limited to theV to be 'accorded'the'full ternally threaded counterbore of larger'diarneter thanthe.
